WebThe four sp 3 orbitals on phosphorus are each able to overlap with an sp 2 orbital on an oxygen atom (forming a tetrahedral framework), while a delocalized fifth bond (a pi bond) is formed by side-by-side overlap of the d orbital on phosphorus with 2p orbitals on the oxygens. The -3 charge on a fully deprotonated phosphate ion is spread evenly ... WebDec 30, 2024 · If we break down the word “phosphodiester”, we see that it quite handily describes the connection: the sugars are connected by two ester bonds ( —O—) with a phosphorous in between. One of the ideas that often confuses students is the directionality of this bond, and therefore, of nucleic acids in general.
